They're required because of that high CapEx. Geothermal projects, unlike wind and solar, have a high CapEx and the return on your investment is.... Our financial modelling for Alberta No. 1 puts our return on investment at about 10% to 15% in that eight- to 10-year time frame. The problem with this is that we are competing directly with investors who are putting their money into hydrocarbons. Those hydrocarbon investments will pay significantly better ROIs than a geothermal project.
There needs to be a population that needs the power or needs the thermal energy. I already mentioned, in answering the other gentleman, that it's not just putting a heat exchanger down into a well; particularly in the case of thermal energy, we have to build a district energy system. Those district energy systems, because we're talking about digging up the ground, are expensive.
Again, we are competing in many localities across Canada with already built infrastructure that is based on natural gas. The best place to put in geothermal is in new development, where we can build that thermal energy requirement or extraction into a new facility.
